1) Click on Create a new model.
2) Under Start in, browse to the folder where you want to save your model.
3) Type the name of the new Model name as projectile_motion and click OK.
4) Make sure that the Gravity is set to Earth Normal (-Global Y) and the Units is set to MMKS - mm,kg,N,s,deg.
1) From the Settings menu, select Working Grid.
2) Set the Size in the X direction to 4000 mm and the Size in the Y direction to 3000 mm and the Spacing in the x and y direction to 50 mm.
3) Make sure that the working grid is oriented along the global XY direction (default setting when you open Adams/View). The Set Orientation pull-down menu allows you to choose Global XY, YZ, XZ, or custom orientation. Click Apply and OK.
1) To create the plane, right-click on the Rigid Body icon and select Rigid Body: Box.
2) Make sure On Ground is selected and enter (3500 mm) for the Length, (100 mm) for the Height, and (100 mm) for the Depth. Also make sure that the Length, Width, and Depth are all checked.
3) Then, right-click on the working grid and then enter in the coordinates for the corner of the plane: 0,-150,0 and then click Apply.
4) To create the spherical stone, right-click on the Rigid Body icon and select Rigid Body: Sphere.
5) Make sure New Part is selected and enter (50 mm) for the Radius. Also make sure that Radius is checked. Then on the working grid select the origin (0,0,0) as the center of the sphere.
1) Right-click on the box (plane), point to Block: BOX_1, and then select Rename.
2) Enter Plane, under New Name, and click Apply and OK.
3) Right-click on the sphere (stone), point to Part:PART_2, and then select Rename.
4) Enter Stone, under New Name, and click Apply and OK.
5) Enter the mass of the stone by right-clicking on sphere and going to Part:Stone, and then selecting Modify.
6) Set Define Mass By to User Input and in the Mass text box, enter 1.0 kg. Click Apply and OK.
1) Right-click on the stone and go to Part:Stone and then select Modify.
2) Under Category select Velocity Initial Conditions.
3) Check X Axis and then enter (6*cos(60d)(m/sec)), and then check Y Axis and enter (6*sin(60d)(m/sec)). Click Apply and OK.
1) Right-click on the stone and select Part:Stone and then select Measure.
2) In the Measure Name text box, enter R_displacement. Set Characteristic to CM Position and Component to X.
3) Make sure Create Strip Chart is checked and select OK.
1) From the Main Toolbox, select the Simulation tool.
2) In the End Time text box, enter 1.5 and in the Step Size text box enter 0.02. Then click on the Play button.
3) After the end of the simulation, click on the Reset tool.
1) From the Main Toolbox, select the Animation tool.
2) Select the Play tool and click on Stop when the stone makes contact with the plane. Use the Step Forward and Step Backward tools, if needed, to facilitate this step. Make note of the time at which the stone makes contact with the plane on the graph.
3) Click on the ellipses above the Icons button and then change No Trace to Trace Marker.
4) In the box, below Trace Marker, right-click and go to Marker and select Browse.
5) In the Database Navigator, under Stone, select cm and then click OK.
1) To find the Stone's Displacement after 1 second, first right-click the blank area inside the stripchart, then choose Plot:scht1 then click on Transfer To Full Plot.
2) In Adams/Postprocessor, from the main toolbar, select the Plot Tracking tool.
3) Because you want to know the final conditions after 1 second, move the cursor over the end point of the plot. In the area below the menu bar, the value of X is displayed as 1. Note the value of Y is -4903.
